UNITED STATES PATENT QFFICEO JAMES OLIVER STAYNER, OF ANGOLA, INDIANA.

WINDMILL.

SPECIFICATION forming part of Letters Patent No. 299,869, dated June 3,1884.

A Application filed February 13, 1884. (No model.)

Be it known that I, J. OLIVER STAYNER of Angola, in the county ofSteuben and State of Indiana, have invented certain new and usefulImprovements in Windmills; and I do hereby declare the following to be afull, clear, and exact description of the invention, such as will enableothers skilled in the art to which it pertains to make and use it,reference being had to the accompanying drawing, which forms part ofthis specification.

My invention relates to an improvement in windmills; and it consists inthe combination of the pumping-rod, which is operated vertically by thewind-wheel in the usual manner,

' and which is provided with a suitable connecting-link with a rack-bar,which is movable horizontally back and forth in relation to thepump-rod, and which is connected with the wind-wheel at its upper endfor the purpose of drawing the mill around out of the wind and stoppingits action, and with a float at its lower end for the purpose of drawingit back out of action with the pumping-rod when the level of the waterhas been lowered, all of which will be more fully described hereinafter.

The object of my invention is to provide an attachment for windmillswhich will automatically throw the wheel out action as soon as asufficient quantity of water has been pumped, and thus prevent anyneedless waste of water or unnecessary work of the mill.

The accompanying drawing represents a side elevation of my invention.

A represents the derrick, and B the pumping-rod, which passes verticallythrough it, and which is connected at its upper end with the crank uponthe inner end of the wheelshaft, in'the usual manner. Also suspended inthe frame by means of arope, cord, wire, or 'chain, 0, which passes upand is connected to the wind-wheel for the purpose of throwing it out ofthe wind, is the rack-bar D, of any suitable length, and which isloosely connected with the pumping-rod by means of the U-shaped frames,guides, or holders F. This rack-bar is supported in position by thecord, wire, or rope O at its upper end, and is connected near its lowerend by means of the cord, wire, or

chain G, which passes over a suitable guidingpulley, H, with theweighted float I, which is placed in the tank into which the water is tobe pumped. When the water has fallen below a certain point, the weightedfloat exerts its whole power in drawing the rack-bar upward and awayfrom the pumping-rod; but when the water has risen to the requiredheight, the weight floats upon the water and slackens the cord 0 to suchan extent that the rack-bar D then swings from its own gravity overtoward the pumping-rod.

Pivoted to the pumping-rod at any suitable point is a coupling-link, J,which is prevented from falling overtoward the rack-bar beyond a certainangle by means of the stop'L. When the rack-bar D is allowed to swingover toward the pumping-rod, the link J catches upon the top of one ofthe ratchets and draws the rackbar downward until one of the othershoulders below catches under the edge of the cross-bar N, which acts asa guide for the pumping-rod. At each successive stroke of the pump-rodthe ratchet-bar is drawn down farther and farther until the wheel isdrawn around out of the wind, and all the movement of the pump-rod isstopped. If one of the ratchets or shoulders of the ratchet-bar did notcatch under the cross-bar, the ratchet-bar would be drawn back inposition as fast as the pump-rod was raised upward; but as theratchet-bar is made to take a fresh hold against the under side of thecross-bar at every downward stroke of the pumping-rod, the ratchet-baris gradually depressed until the wheel is drawn around out of the wind.As soon as the wheel is drawn around out of the wind, the movement ofthe pumping-rod ceases, and the rack-bar remains depressed as long asthe water maintains a level above a certain point. As soon as the waterfalls below this level,the weighted float I pulls the'rack-bar Dsidewise beyond the reach of the coupling-link J, and the weight of thewheel instantly causes it to swing around into the wind again. Thisaction is repeated as often as the tank is filled and the water drawnoff.

Having thus described my invention, I claim--- The combination, with thevcrtica1ly-1novthe tank into which the Water is pumped, subingpumping-rod of a windmill and a constantially as shown and described.necting-latch which is loosely attached thereto, In testimony'whereof Iaffix my signature in of a ratchetbar which has both a vertical and apresence of two witnesses.
